PURPOSE: A compact electronic active mount is provided to reduce impact and vibration because additional coil and permanent magnet can be located to get strong driving force by changing a structure. CONSTITUTION: A compact electronic active mount comprises a first steel core(61), a second steel core(62), a first permanent magnet(51), a cylindrical driving unit, a first coil(81), and a second coil(82). The second steel core is located separately from the first steel core and the exterior periphery is fixed in an inner surface of a housing. The first permanent magnet is connected to the second steel core to be fixed. The cylindrical driving unit is extended upward from a space where the first and second steel cores are separated. The second coil covers lower periphery of the driving unit.
